TO ALL WHOM ,IT MAY CONCERN:

Be it known that I, Lnnnnnn W. Born'roy, of the city and countyof-Harttord, in the State of Connecticut, have invented a newand usefulimprovement in Machinery or Apparatus for Preparing Peat for Fuel; and Ido hereby declare that the following is a full, cle ar, and exactdescription of the construction, character, and operation of the same,reference heinghad to the accompanying drawings, which make partof thisspecification, in which- Figure 1 is a'perspective viewed the machine orapparatus with the cover removed showing the internal parts.

Figure 2 is a longitudinal section of the same, cut vertically throughthe centre, showing the several parts in their relative positions.

My improvement consists in the use of spurred .rollers, &c., to tear upor loosen the peat; two or more cylinders revolving with unequalvelocity, so as to grind the peat as it passes through; an endless apronto carry the peat through the steam ohamber; a perforated. steam pipethrough which I admit high steam to dry the peat; a fan to exhaust'thcair, &c.,-from the steam chamber; spurred rollers to again breakup orloosen the peatj a cylinder with moulds in its convex surface in,-whichpistons work from the centre to press the peat against a bar; and anendless apron to carry the bricks or blocks of dried and pressed peatthrough the warmair chamber from which it will fall into a suitablereceptacle 1 make the box'A AA, which contains the whole apparatus, ofcast iron or any other suitable material, substantially in the 'formrepresented in fig. 1, and indicated in section in fig. 2. At theright-hand end of this box A A A I fit a suitable hopper, with a steamchamber near the bottom, as B, to'receive the newly dug or unpreparedpeat and disch'a'r'geit into the working machinery to be prepared forfuel. I make the spurred rollers as represented at a a, and revolvethcm'by belts as indicated by pulleys, at a, fig. 1, or by gear-wheels,so as to tear up or loosen the new dug peat; or, one' rollerands/spurred apron may be used. I make the grindingcylinders b and c ofcast iron, or any other suitable material, of the same diameter, and, bymeans of belt or gear-wheels, revolve them in different times, or makethem of difi'erent diameters and revolve them in equal times, so as toproduce not only a pressing but grinding operation. I fit an endlessapron, as indicated by red ,dots at d d, figs. and 2, which I run onrollers, as c and-'f, and steady it by the rollers g it i, to carry thepeat forward through the steam chamber. Centrally and within this aprond d, I place a perforated steam pipe as j, (figs. 1 and 2,) at either orboth ends of which I introduce high steam, (say four to six or moreatmospheres,) so that its superabundant heat will convert the moisturein the peat into steam, when the whole of the steam will be carried offby its own levity and pressure, and the efi'ectof the exhaust-fan C inthe eupola,

as shown in fig. 2. I make the spurred rollers 7c and Z in the usualway, as represented in figs. land 2, and revolve them inwardly to breakand pulr erize the partially dried peat before it falls into the mouldsin the cylinder .D. I make the moulding cylinder'iD with its rows ofmoulds, pistons, cams, 850., substantially as d'escribed'and setforth inmy patent for making mould sugar, issued December, 27, (antedated 15,)1864, causing the pistons-to press the rows of'hlocks against a bar, asE,- figs. 1 and 2. (Or, I use another cylinder, as described in mybeforementioned patent.) I make the endless apron F in the'usual way,and work it on rollers, as m and 1|, to carry the blocks from themoulding and pressing cylinder D, through the war1n-air chamber G, tocomplete the desiccation of the-peat. 'lo beat this chamber G, Iinsert atube to pass in a zigzag way, as indicated at 10, figs. 1 and 2, from rto a, into which I introduce steam or liot air, asconvenience mayrequire. And, it thought beat, any or all of the rollers may be madehollow and filled with steam or hot air, especially in cold weather tothaw out the work, or keep it'from freezing at night, or to warm it forgeneral purposes. Having made the several parts and arranged them asbefore described, I put the machine in motion by any convenient power,admit the high steam into the perforated pipe or tube j, .(at either. orboth cnds,) and let steam or hot air into either end, 1' or a, of thezigzag pipe 11. I then put the newly dug peat into the hopper B, whenthe spurs on the rollers a a, (or roller and apron,) will'tear upand'loosen the peat and allow it to fall between the rollers b and c,where, by the unequal motion of theirsurfaccs, the peat will bepressed'and ground into a homogeneous mass and fall upon the endlessapron d, which will carry it up to. the next spur-rollers 7c and Z,while the high steam admitted through thepert'orated tubej, will, by itssuperabundant heat, convert the moisture in the peat into steam, whichwill all he carried or? through the outlet or cduction spout w, so thatthe peat will bo as dry as the steam used, antlin a good condition formoulding. In this condition it will fall into the moulds in the surfaceof the moulding cylinder D, and, when any one of the rows of moulds comeunder the bar E, the pistons will be forced outward so as to press thepent into 'a solid block, end as the row passes the bar E, the pistonwill force the block out onto the endless apron I, by which it will becarried through the dry-air choniber,

nnd fall out upon the slide H ready for ,use or market. Thus, the wholework is done in the most eflicie'nt manner, at very little expense andin a very brief spnceof time. As ai more particular description of thehopper B, I make the spurred apron. or lower portion of the rear perthollow, as represented at L, fig. 2, to

receive stezun to keep that part of the machine warm when so needed.

What I claim as my' invention, zind'dcsire to secure by Letters Patent,is

1. The combination of the grinding cylinders "'c and b, with the spurredrollers, (orioller and spurred apron,) and hopper B, and when they areconstructed, arranged, and fitted for use, substantially as hereindescribed and set forth.

2. I claim the combination of the perforatedpipej for'the high steam,with the apron d (l, and the exhaust fan U, when they are constructed,arranged, nnd-fi tted-for carrying and drying the peat, substantially asherein described and set forth.

3 1 claim the moulding and pressing cylinder D,-(as described in mypatent issued December 27, 1864,) in combination ivith the apron F, andzigzag pipe p, when they are constructed, arranged, and fitted formoulding, pressing, and dryingpcat, substantially as herein describedand set forth.
